The mounting component further includes a shearing unit. The shearing unit includes a shearing support seat 31, two shearing driving components 32, a support shaft 33 and two shearing blades 34.

[0036] Among them, an insulating layer 3 and a wire core 4 are respectively placed on the two placement seats 1, a plurality of the rollers 2 are sequentially arranged inside the two placement seats 1, both the insulating layer 3 and the wire core 4 are located above the rollers 2, the bottom moving unit is arranged below the two placement seats 1, a plurality of the piercing rods 5 penetrate through the insulating layer 3 in a surrounding manner, a plurality of the clamping blocks 6 are all arranged on the piercing rods 5, and a plurality of the pulleys 7 are sequentially arranged around one end of the wire core 4. One end of the insulating layer 3 and the wire core 4 are respectively placed on the two placement seats 1, and the other end is unwound by a pay-off machine; one end of the piercing rod 5 is inserted into the insulating layer 3, and then the clamping block 6 pops out to limit the piercing rod 5; a plurality of the piercing rods 5 rotate in the same direction simultaneously to expand the pierced end of the insulating layer 3; the bottom moving unit adjusts the distance between the insulating layer 3 and the wire core 4, and through the expanded area, the wire core 4 smoothly enters the inside of the insulating layer 3; the head of the wire core 4 contacts the inner wall of the insulating layer 3 through a plurality of the pulleys 7 and continuously extends into the insulating layer 3 until the unwinding is completed, and the installation of the insulating layer 3 is completed; in addition, when the insulating layer 3 and the wire core 4 are conveyed, the rollers 2 contact the lower part thereof to avoid large friction with the placement seats 1.

[0037] Secondly, two of the symmetric moving mechanisms are arranged below the placement seat 1, and two of the moving plates 8 are arranged above the two symmetric moving mechanisms; the groove body 9 is arranged below the placement seat 1, the driving component 10 is arranged at one end of the groove body 9, the connecting shaft 11 is located inside the groove body 9, one ends of two of the threaded rods 12 are symmetrically arranged at both ends of the connecting shaft 11, and the other ends of the two threaded rods 12 are rotatably connected to the groove body 9, the output end of the driving component 10 is fixedly connected to the other end of the corresponding threaded rod 12, two of the threaded blocks 13 are respectively adapted to the corresponding threaded rods 12, and two of the moving plates 8 are respectively arranged above the corresponding threaded blocks 13. The groove body 9 supports the entire symmetric moving mechanism, the driving component 10 is a motor, when the driving component 10 is started, it drives the threaded rod 12 to rotate, due to the connection of the connecting shaft 11, two symmetric threaded rods 12 rotate simultaneously, cooperate with the threaded blocks 13, so that the threaded blocks 13 move, and further the moving plates 8 move, and finally the positions of the two placement seats 1 are adjusted to make the wire core 4 and the insulating layer 3 approach each other and adjust the distance.

[0038] Meanwhile, the puncture support unit is disposed above the corresponding moving plate 8; the support frame 14 is fixedly connected to the placement seat 1 and is located above the placement seat 1. A plurality of puncture telescopic members 15 are sequentially disposed inside the support frame 14. The output ends of the plurality of puncture telescopic members 15 are respectively fixedly connected to the corresponding puncture rods 5. A plurality of puncture rotating members 16 are rotatably connected to the inner wall of the support frame 14. The output ends of the plurality of puncture rotating members 16 are respectively rotatably connected to one side of the corresponding puncture telescopic members 15. A plurality of push mechanisms for the clamping blocks 6 are respectively disposed inside the corresponding puncture rods 5. The support frame 14 supports the entire puncture support unit. The puncture telescopic member 15 is a self-locking cylinder, and the puncture rotating member 16 is a self-locking cylinder. When puncturing, one end of the insulating layer 3 is moved inside the support frame 14, and then the puncture telescopic member 15 is activated to drive the puncture rod 5 to insert into the insulating layer 3. At this time, the clamping block 6 extends out to limit the puncture rod 5 to prevent it from detaching. Then, the output end of the puncture rotating member 16 contracts, causing the puncture telescopic member 15 to rotate, thereby driving the puncture rod 5 to rotate outwards, so as to expand one end of the insulating layer 3, making it more convenient for the head end of the core 4 to enter and avoiding the situation of abutment or friction during entry.

[0039] In addition, the puncture rod 5 has a groove 24. The two ends of the first spring 17 are respectively movably connected to the inner top wall of the groove 24 and one end of the cone 19. The two ends of the telescopic rod 18 are respectively fixedly connected to the inner top wall of the groove 24 and one end of the cone 19. The first spring 17 is sleeved outside the telescopic rod 18. The first electromagnet 20 is disposed at the other end of the cone 19. The second electromagnet 21 is located at the inner bottom wall of the groove 24. Two fixing plates 22 are respectively disposed on one side of the corresponding clamping block 6. The two ends of the two second springs 23 are respectively movably connected to the corresponding fixing plate 22 and the inner side wall of the groove 24. The clamping block 6 is slidably connected to the groove 24. When the clamping block 6 pops out, the first electromagnet 20 and the second electromagnet 21 are energized, thereby driving the cone 19 to move downward, thus pushing the two clamping blocks 6 to slide outwards. Then, the first electromagnet 20 and the second electromagnet 21 continue to be energized to keep the clamping block 6 stable. When retraction is required, the electromagnets are de-energized, and then the first spring 17 contracts, driving the cone 19 to return and rebound. At the same time, the telescopic rod 18 follows and contracts to maintain stability. At this time, the second spring 23 rebounds, and through the fixing plate 22, drives the clamping block 6 to rebound and reset.

[0040] Then, both of the two mounting shells 25 are sleeved outside the core 4, and the two mounting shells 25 are bolted together. A plurality of core 4 moving units are sequentially arranged on the corresponding placement seats 1. The abutting member 26 is arranged on one side of the placement seat 1. The output end of the abutting member 26 penetrates through the placement seat 1 and is fixedly connected to the U-shaped plate 28. The pressure sensor 27 is arranged at the output end of the abutting member 26. The core driving member 29 is arranged on one side of the U-shaped plate 28. The output end of the core driving member 29 penetrates through the U-shaped plate 28 and is fixedly connected to the core moving wheel 30. After the two mounting shells 25 are sleeved and installed at the head end of the core 4, they support the plurality of pulleys 7. Furthermore, the pulleys 7 are in contact with the inner wall of the insulating layer 3, avoiding friction between the head end and the inner wall when moving inside the insulating layer 3. When the core 4 is conveyed into the insulating layer 3, the abutting member 26 is started to drive the U-shaped plate 28 to move. When the value of the pressure sensor 27 changes, it means that the core moving wheel 30 comes into contact with the core 4. At this time, the core driving member 29 is started to drive the core moving wheel 30 to rotate, thereby driving the core 4 to move and gradually conveying it into the insulating layer 3. Among them, the abutting member 26 is a self-locking cylinder, and the core driving member 29 is a motor.

[0041] Again, the shearing unit is arranged above the corresponding placement seat 1. The shearing support seat 31 is arranged above the corresponding placement seat 1. Both of the two shearing driving members 32 are rotatably connected to the shearing support seat 31 and are symmetrically distributed inside the shearing support seat 31. The output ends of the two shearing driving members 32 are respectively rotatably connected to one end of the corresponding shearing blade 34. The support shaft 33 is arranged above the shearing support seat 31. The two shearing blades 34 are rotatably connected through the connecting shaft 11. The shearing support seat 31 supports the entire shearing unit. The shearing driving member 32 is a cylinder. When the conveyance of the core 4 is completed, at this time, the head end of the core 4 extends out from the other end of the insulating layer 3. Furthermore, the mounting shell 25 and the pulley 7 are removed. At the same time, the output end of the shearing driving member 32 extends out, driving the two shearing blades 34 to rotate on the support shaft 33. Furthermore, the shearing blades 34 trim the punctured end of the insulating layer 3, avoiding the punctured end from affecting the appearance and insulating effect of the insulated cable.

[0042] When using an insulating cable production device according to this embodiment, one end of the insulating layer 3 and the wire core 4 are respectively placed on the two placement seats 1, and the other end is unreeled by an unreeling machine; when one end of the insulating layer 3 moves inside the support frame 14, the puncture telescopic component 15 is started to drive the puncture rod 5 to insert into the insulating layer 3. At this time, the clamping block 6 extends out to limit the puncture rod 5 to prevent it from disengaging. Then, the output end of the puncture rotating component 16 contracts, causing the puncture telescopic component 15 to rotate, and further driving the puncture rod 5 to rotate outwards, so as to expand one end of the insulating layer 3; at this time, the driving component 10 is started to drive the threaded rod 12 to rotate. Due to the connection of the connecting shaft 11, the two symmetric threaded rods 12 rotate simultaneously, cooperate with the threaded block 13, causing the threaded block 13 to move, and further causing the moving plate 8 to move, finally adjusting the positions of the two placement seats 1, making the wire core 4 and the insulating layer 3 approach each other, adjusting the distance, and passing through the expanded area, so that the wire core 4 smoothly enters the insulating layer 3; the head of the wire core 4 contacts the inner wall of the insulating layer 3 through a plurality of pulleys 7 and continuously extends into the insulating layer 3 until the unreeling is completed, completing the installation of the insulating layer 3; in addition, when the insulating layer 3 and the wire core 4 are conveyed, the roller 2 contacts the lower part thereof to avoid large friction with the placement seat 1;

[0043] Through the above structural settings, first, by using the operations of puncturing and rotating, the opening of the insulating layer 3 is expanded, and then the wire core 4 smoothly enters the insulating layer 3, reducing the damage suffered by the wire core 4 and the insulating layer 3 due to inaccurate docking during sleeving, and at the same time improving the sleeving efficiency; and also relying on the function of the pulley 7 to avoid large friction when the head end of the wire core 4 moves inside the insulating layer 3, thereby avoiding scratches or damage on the inner wall of the insulating layer 3 and improving the production quality of the insulating cable.

[0044] Please refer to Figure 8 , the present invention also provides an insulating cable production method, including the following steps:

[0045] S1: One end of the insulating layer 3 and the wire core 4 are respectively placed on the two placement seats 1, and the other end is unreeled by an unreeling machine;

[0049] S5: The head of the wire core 4 contacts the inner wall of the insulating layer 3 through a plurality of the pulleys 7 and continuously extends into the insulating layer 3 until the unwinding is completed, thus completing the installation of the insulating layer 3.

[0050] Wherein, one end of the insulating layer 3 and the wire core 4 are respectively placed on the two placement seats 1, and the other end is unwound by an unwinder; the puncture rod 5 is inserted into one end of the insulating layer 3, and then the clamping block 6 pops out to limit the puncture rod 5; a plurality of the puncture rods 5 rotate in the same direction simultaneously to expand one end of the insulating layer 3 that has been punctured; the bottom moving unit adjusts the distance between the insulating layer 3 and the wire core 4, and through the expanded area, enables the wire core 4 to smoothly enter the inside of the insulating layer 3; the head of the wire core 4 contacts the inner wall of the insulating layer 3 through a plurality of the pulleys 7 and continuously extends into the insulating layer 3 until the unwinding is completed, thus completing the installation of the insulating layer 3.
